The market is inching toward fresh highs, but the foundation looks a lot shakier than the celebration suggests. Between sentiment readings that scream irrational exuberance, a consumer base stretched to its breaking point, and an AI boom that’s burning cash faster than it’s generating profits, 2026 is shaping up to be the year where reality catches up with optimism.

Subramanian warns that monetization remains unproven and that power constraints will take time to solve.

• Tech debt supply has ballooned to ten times last year’s level as hyperscaler capital intensity jumped from 13% in 2012 to 64% today, showing just how expensive the AI build-out is.
• Since the S&P 500’s Oct. 28 peak, Information Technology is down 4.2%, with MetaMETA
